Looks better in person, my lighting sucks but I didn't want to wait until tomorrow's daylight to post this As soon as I saw the letter in the mailbox I told my wife "this looks like coming from the 1960's". Boy I wasn't so wrong! So she told me, let's do a little research. And this was the outcome. We put the years next to the stamps. Mind blowing! Thanks a lot @lordmarcovan ! You made us both very happy!
